Setting Scaling Upper and Lower
Limits for Analog Inputs
z
Analog Input
• When an analog input is selected, scaling can be performed as needed by the
control application.
• Scaling is set in the Scaling Upper Limit, Scaling Lower Limit, and Decimal
Point parameters (Initial Setting Level). These parameters cannot be used
when a temperature input is selected.
• The Scaling Upper Limit parameter sets the physical quantity to be expressed
by the upper limit value of input, and the Scaling Lower Limit parameter sets
the physical quantity to be expressed by the lower-limit value of input. The
Decimal Point parameter specifies the number of digits below the decimal
point.
• The following figure shows a scaling example for a 4 to 20 mA input.
After scaling, the temperature can be directly read. Here, one place below the
decimal point is set.
In this example scaling is set to display 4 to 20 mA as 10.0% to 95.0%.
